Technical Field

[0001] This utility model relates to the field of mud-water separation technology, specifically to a device for separating sludge and water in biogas digesters. Background Technology

[0002] Biogas is produced from straw and manure, and the effluent is sludge. After separating the sludge from the water, the solids can be used as plant substrate or fertilizer. However, when traditional separation equipment removes the sludge, some of it tends to remain inside the equipment. Therefore, a sludge-water separation device for biogas digesters has been proposed to solve this problem. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] In the embodiments, by Figure 1 A device for separating sludge and water in a biogas digester is provided, comprising a support frame 1, three saddles 2 mounted on the top of the support frame 1, a separation tank 3 fixedly connected to the top of the three saddles 2, an inlet pipe 4 provided at the top of the separation tank 3, an outlet pipe 5 provided at the right end of the separation tank 3, and a sludge top cover 6 threadedly connected to the inner side of the separation tank 3.

[0021] With the above setup, rotate the sludge top cover 6 to fix it relative to the separation tank 3. Add an appropriate amount of sludge-water mixture into the separation tank 3 through the inlet pipe 4. After standing for 48 hours, use a water pump to pump the settled liquid out from the outlet pipe 5 (note that a filter screen is installed at the inlet of the outlet pipe 5 to prevent some sludge from entering the outlet pipe 5). Then rotate the sludge top cover 6 (note that the inlet pipe 4 should be kept connected to the outside during this process to avoid the inability to rotate the sludge top cover 6 due to atmospheric pressure). Use a shovel or other tools to shovel out the sludge at the bottom of the inner cavity of the separation tank 3. Finally, the remaining sludge is rinsed clean with a high-pressure water gun. Compared with existing technologies, all the sludge can be cleaned out of the separation tank 3. It should be noted that this device achieves solid-liquid separation by sedimentation, so the separation efficiency is not high. Generally, several devices need to be connected in series to achieve the required separation effect. However, this device requires less energy than centrifugal separation devices and is a green and environmentally friendly separation device.

[0022] Reference Figure 1 Among them, two handles 7 are fixedly connected to the left end of the sludge top cover 6;

[0023] With the above-mentioned structural design, the handle 7 can easily grip and move the sludge top cover 6, making both opening and closing much easier.

[0024] Reference Figure 1 Among them, the left end of the support frame 1 is fixedly connected to the mud guide plate 8, and the mud guide plate 8 is fixedly connected to the top end of the support frame 1;

[0025] With the above structural design, the mud guide plate 8 can guide the mud to flow in a certain direction and path, and to the target location for collection.

[0026] Reference Figure 1 Among them, the mud-guiding surface of the mud-guiding plate 8 is an arc surface;

[0027] With the above structural design, the arc-shaped mud guide surface can guide the mud to flow more smoothly. Compared with the flat mud guide surface, the arc-shaped mud guide surface can reduce the resistance and friction of the mud during the flow process, making it easier for the mud to slide down along the mud guide surface, thereby improving the flow efficiency of the mud. In addition, the arc surface can reduce the mud from falling off the sides of the mud guide plate 8 compared with the flat surface.

[0028] Reference Figure 1 Among them, the top of the separation tank 3 is equipped with two lifting lugs 9;

[0029] With the above structural design, the lifting lug 9 is the main connection point for vertically hoisting the separation tank 3. By using the lifting lug 9, the separation tank 3 can be easily moved and installed using hoisting equipment (such as a crane or hoisting machine). Especially when it is necessary to move the separation tank 3 from one location to another, the existence of the lifting lug 9 greatly simplifies the operation process.

[0030] Reference Figure 1 The saddle 2 is fixed to the support frame 1 by bolts;

[0031] With the above structural design, the main function of the saddle 2 is to support the weight of the separator 3 and fix it in the appropriate position. This function ensures the stability and safety of the separator 3 during operation.
